I own a WD3200KS-00PFB0 (ie, the old standard SE16 320), and I wanted to add a second matched drive from a different batch as a raid set. However, for almost two months, the 3200KS was completely unavailable and now they've started shipping again. It seems likely the new ones have 2x 160 platters instead of 2.5x133. Can anyone confirm? If they are, I'd probably be better off getting two new drives.
